摘要

安全半量子求和需要在量子第三方的协助下，由多个不可信且资源有限的参与者集体计算私人秘密的总和。本文介绍了三种基于单光子的半量子求和协议，消除了经典用户对测量能力的需求。双方协议 1 和协议 2 分别基于不同的模型：星形和环形。安全分析广泛评估了协议对外部和内部攻击的抵御能力，证明协议是渐进安全的。协议 3 将两方协议 1 扩展到多方场景，扩大了其适用范围。通过比较发现，与以前的类似协议相比，经典用户的工作量有所减少，协议的正确性也通过 Qiskit 的模拟得到了直观验证。

Different secure semi-quantum summation models without measurement

Secure semi-quantum summation entails the collective computation of the sum of private secrets by multi-untrustworthy and resource-limited participants, facilitated by a quantum third-party. This paper introduces three semi-quantum summation protocols based on single photons, where eliminating the need for classical users to possess measurement capabilities. Two-party protocol 1 and protocol 2 are structured upon different models: star and ring, respectively. The security analysis extensively evaluates the protocols’ resilience against outside and inside attacks, demonstrating protocols are asymptotically secure. Protocol 3 extends two-party protocol 1 to multi-party scenarios, broadening its applicability. Comparison reveals a reduction in the workload for classical users compared to previous similar protocols, and the protocols’ correctness are visually validated through simulation by Qiskit.
